Numerical simulation of underground Seasonal Solar Thermal Energy Storage (SSTES) for a single family dwelling using TRNSYS

► Study of reduction in traditional heat demand of a single family home. ► Artificial storage bed stores solar thermal energy from the summer for winter use. ► Practical optimum size for the storage bed, solar collector area, and fluid flow rate. ► We conclude seasonal solar thermal energy storage is a feasible method to provide winter space heat.
